Class PointQuadtree

Implements a spatial subdivision tree to work efficiently with large numbers
of 2D particles. This quadtree can only be used for particle type objects and
does NOT support 2D mesh geometry as other forms of quadtree might do.
For further reference also see the QuadtreeDemo in the /examples folder.

getMinNodeSize

public float getMinNodeSize()

Returns the minimum size of nodes (in world units). This value acts as
tree recursion limit since nodes smaller than this size are not
subdivided further. Leaf node are always smaller or equal to this size.
